Considering the importance of Urumieh Dokhtar Magmatic Arc (UDMA) from geodynamical and metallogenic perspectives, is noteworthy the necessity of comprehensive petrogenetic study on it and comparison them with the results so far, especially that there has been no such study on dating, and petrogenetic relationships. On the other hand, the coexistence of fertile (economic and sub-economic) porphyry Cu rocks and barren intrusive rocks in this belt provides a good path to study these systems and to determine factors of mineralization by comparing fertile and barren igneous rocks. Metal stable isotope studies such as Cu have proven a novel tool for better understanding mineralization processes in hydrothermal deposits. In this project, we assess the Cu isotopic values of porphyry Cu deposits from the UDMA. Also using petrographic, geochemical, Sr-Nd-Hf isotopes could be a suitable way to understand the complicated history of these parts of the UDMA of Iran.
